Ewe/ 1/51, ZAGZfl/V/fl United States Patent 3,451,760 GAS MANTLE HOLDER Enrique L. Laguinia, 1019 Ongpin St., Manila, Philippines Filed Aug. 24, 1967, Ser. No. 662,915 Int. Cl. FZlh 7/00 US. Cl. 431-112 1 Claim ABSTRACT OF THE DISCLOSURE The present invention relates to an improved gas man tle holder adapted to be supported or hung from a conventional lamp receptacle, and more particularly the invention relates to an improved mantle holder construction in which the mantle is always tied hanging to the holder body and leaving the portion thereof without support.

Since the burned mantle is fragile it breaks easily. The gas vapor comes from a very small area resulting in poor gas distribution. The necessity of hanging the mantle limits the range of lantern design. In the improvement of the present invention, a novel and simple support is provided so that the modified mantle can be tied firmly and evenly at both ends to a support hollow material body. The long cylinder body has perforations which give a more even distribution of gas vapor and the correct distance between the gas ports and the mantle is predetermined to give optimum brightness. Since the mantle can be firmly held at both ends, a radical change in lantern design can be made more simply and economically, including having it supported from a conventional electrical lamp type receptacle.

Reference will now be made to the accompanying drawings which illustrate a mantle mounting constructed in accordance with the preferred embodiment of the present invention and in which:

FIGURE 1 shows a front elevational view, partly broken away, of the improved gas mantle holder of the present invention.

FIGURE 2 shows details of the gas mantle holder, partly in section, and enlarged from the mantle shown in FIGURE 1.

FIGURE 3 is a modified construction of the body we cone configuration for eliminating shadows occurring below the device when used as a gas mantle holder. 7

FIGURE 4 is a further embodiment wherein the body is formed of a series of elements, and

FIGURE 5 is a modified arrangement in which the gas mantle holder is of T-shaped construction.

Referring now to the drawings, there is shown a gas lamp having a cylindrical hollow material body 12 with perforations 14 as shown in detail in FIGURE 2, and having a threaded portion at the upper end of the body for engaging with the threaded portion of a conventional electric lamp type receptacle (not shown). At upper and lower extremities of the material body 12 are land extending portions 16, 18 with grooves 20, 22 for receiving a bulbous mantle 26. The mantle is secured or tied onto the land portions 16, 18 by a wire or other thread member 30, 3-2 for retaining or generally securing the mantle in the grooves 20, 22 of the land portions.

In FIGURES 2-5, the threaded portion 34 is shown for engaging the conventional electrical lamp type receptacle mentioned above.

In FIGURE 3, the hollow material body 36 terminates in a conical shaped element having perforations 38. Land portions similarly identified as 16, 18 having grooves 20, 22 respectively for receiving the mantle 26, are illustrated. A tying element 30, 32 for securing the mantle 26 onto the land elements 16, 18 is shown.

In FIG. 4 there is provided an extended or series arrangement of hollow material bodies 40, 42 with end and intermediate land portions 44, 46, 48 and with their respective grooves, to which is secured the mantle 50. The mantle 50 is seen as secured by wires 52, 54, 56. The land 48 is seen to extend as a terminal or closure member for the hollow material body 42. The bodies 40 and 42 each have perforations similar to that described in FIGURES 1 and 2.

The hollow material body may have a T-shaped construction as is illustrated in FIGURE 5 in which the threaded portion 34 extends into end hollow bodies 60, 62 with their respective land portions 64, 66, land portion 66 forming a plug or closure for the hollow material bodies 60, 62. Perforations of conventional construction shown in FIGURES 24 are also provided as shown. To the land portion 64, 66 are secured mantles 70, 72 of conventional screen construction which are held to the land portions by wires 74, 76, 78 and 80 to grooves of the land portions, as shown.

In operation, gas vapor passes into the open end of the hollow material body next to the threaded portion 34 and out through the gas perforations such as 14 described in FIGURE 2 and referred to in the other FIGURES 3-5. The apparatus provides a better distribution than conventional types of mantle arrangements, and is adapted for support from types of conventional electric fixtures made to simulate the actual components.

What is claimed is:

1. A gas mantle holder comprising a cylindrical hollow material body open at an end and closed at the other end, a threaded portion at said one end adapted to engage with the threaded portion of the lamp type receptacle, land portions circumferentially extending about end and intermediate portions of said cylindrical body, and a mantle of bulbous construction secured at an intermediate location to an intermediate land and at its distal extremities to said end land portions, said land portions having grooves for tying the mantle to said land portions in surrounding relation to the respective portions of the cylindrical body between pairs of lands, and body having perforations between pairs of lands for the passage of gas to the respective bulbous portions of said mantle.
